Thanks! I do appreciate your advice. I adopted him from the Human Society last year and I now know why I'm his 3rd owner...litter box problems. I've spent a lot of money at different vets. He's going to be 9 in October. I know that I'm sometimes overprotective with him but I just want him to be happy and healthy. I'm going to go home and check on him at lunch time and see how he's doing. If you think of anything else I should try let me know!

Thanks for answering!
